[0031] see figure 1 and figure 2 , propose the first embodiment of the gesture recognition method of the present invention, this embodiment includes the following steps:

[0032] Step S101, creating a screen coordinate system;

[0033] Step S102, collecting the spatial motion trajectory of the gesture, and mapping the motion trajectory to the screen coordinate system. In this step, the gesture movement trajectory refers to the movement trajectory of the center of mass of the hand. That is, the motion trajectory of the gesture refers to the motion trajectory of the center of mass of the hand from the start point of the movement to the end point of the movement.

[0034] Step S103, constructing a straight line between the starting point and the end point of the motion, calculating the angle α between the straight line and the horizontal axis of the screen coordinate system, and judging the The direction of motion of the gesture.

[0035] see figure 2 , in this step, the ...

Abstract

The invention discloses a gesture identification method and a gesture identification device. The gesture identification method comprises the following steps of: creating a screen coordinate system; acquiring a gesture moving trace, and mapping the moving trace into the screen coordinate system; constructing a straight line from a moving start point to an end point, and calculating an included angle alpha between the straight line and the transverse axis of the screen coordinate system; and judging a moving direction of a gesture according to the included angle alpha and coordinate values of the moving start point and the end point. The gesture identification method and the gesture identification device are simple and are low in cost.

Description

technical field [0001] The present invention relates to the technical field of gesture recognition, in particular to a gesture recognition method and a gesture recognition device. Background technique [0002] At present, the means for users to interact with TVs are becoming more and more diverse, from TV buttons and remote controls to voice and gestures. Gesture operation TVs are generally divided into static gestures and dynamic gestures. Static gestures refer to the static gestures of the user, and then the camera captures the gestures of the hands and responds differently according to different gesture definitions; dynamic gestures are judged by the trajectory of the hand Gestures. [0003] Existing gesture recognition uses spatial algorithms to calculate the spatial trajectory of gestures, and the algorithms are complex and costly. Contents of the invention [0004] The main purpose of the present invention is to provide a gesture recognition device and a gesture re...
